Product Description
CMC-SX motor soft starter is a new type motor starting and protection device that is integrated with power electronic technology, microprocessor and automatic control. This soft starter is able to steadily start and stop motor without step change so as to avoid mechanical or electric impact resulted from using conventional starting modes such as direct starting, star-delta starting and auto voltage reducing starting, and effectively reduce starting current and distribution capacity for fear of more investment on capacity expansion.
Multiple start mode

Choiceable current limit start, voltage exponential curve start, voltage linear curve start, current exponential curve start and current liner curve start with optional programmable kick-torque and current limit for each mode. Customer may choose different start mode for various application and start your motor in the best way. More accuracy and smoothness for start and stop due to application of the particular algorithm pattern.
Dual parameter function
This function allows you to start two motors of different power separately by one CMC-SX with two sets of independent parameters which will reduce your inventory investment.
Advanced communication function
CMC-SX provides a RS485 interface port, which enables collective control for customer, improves system automatization and reliability. The integrated standard Modbus protocol makes an easy configuration.
★Multiple starting modes
Current-limiting start, ramp current-limiting start and voltage ramp start can meet the site requirements to the maximum extent and realize the best starting effect.
High reliability
High performance microprocessor conducts digital processing for signals in control system, avoiding the excessive adjustment to analog line so as to obtain the best precision and execution speed.
Powerful anti-interference performance
All external control signals adopt optoelectronic isolation and are set with different anti-noise levels. The device is applicable for use in special industrial environment.
Optimized structure
The unique compact structure is designed to be easily integrated into user's existing system, saving expenses for restructuring of system.
Motor protection
Multiple motor protection functions such as over-current, input/output phase-failure, short circuit of thyristor and overheat protection can guarantee motor soft starter not to be damaged in case of fault or incorrect operation.
Easy maintenance
Pilot signal coding system composed of 4-digit number display monitors working condition of the system for 24 hours and meanwhile provides quick fault diagnosis.

Cooling PatternNatural wind cooling
Place to be usedIndoor location with good ventilation free from corrosive gas and conductive dust.
Enviroment ConditionBelow 2000M. It have to rise the rate power when the altitude is more than 2000M.
Ambient Temperature -25+45°C
Ambient Humidity 95%(20°C±5°C)
Dust: If too much dust, it will reduce the insulation level of the soft starter, even causes the soft starter does not work.
Brush the dust with clean and dry brush.
Remove dust with compressed air machine.
2. Condensation: If condensation, it will reduce the insulation level of soft starter, even causes the soft starter does not work.
(1)  Blow it with a hair dryer or electric stove.
(2)  Bring it to power distribution room for dehumidification.
3. Regularly check components' intact. Whether it can work properly.
4. Check soft starter' cooling channel, ensure they are not clogged by dirt and dust.
Before maintenance checking, it has to cut off all power in the line side of soft starter.
